( | x | − | ( | x | − | 11000 | ) | × | 13 100 | × | 28 25 | ) | = | 11000 | ÷ | 18 25 |
方程左边 = | x | − | ( | x | − | 11000 | ) | × | 13 100 | × | 28 25 |
= | x | − | ( | x | − | 11000 | ) | × | 91 625 |
= | x | − | x | × | 91 625 | + | 11000 | × | 91 625 |
= | x | − | x | × | 91 625 | + | 8008 5 |
= | 534 625 | x | + | 8008 5 |
534 625 | x | + | 8008 5 | = | 11000 | ÷ | 18 25 |
方程右边 = | 137500 9 |
534 625 | x | + | 8008 5 | = | 137500 9 |
534 625 | x | = | 137500 9 | − | 8008 5 |
534 625 | x | = | 615428 45 |
x | = | 615428 45 | ÷ | 534 625 |
= | 615428 45 | × | 625 534 |
= | 307714 9 | × | 125 267 |
x | = | 38464250 2403 |
